My CV conversion is still coughing a little bit when I let off the gas at highway speeds. Does anyone have an idea on jets needed for an 89 Electra glide w/CV. Stock air cleaner and some Kerker pipes?

Separate note: the bike also vibrates quite a bit more when I squeeze the brake at a stop light. Any ideas on that?

 

If popping thru exhaust when letting off,check for tightness of exhaust at heads. When grabbing front brake it freezes wheel and doesn't absorb vibration the same.

 

Thanks that explains the vibration. The coughing is through the carb. It happens when I am too low in gear.

 

Usually means your pilot (or slow jet) is lean...what size do have in there now?

 

I am not positive what is in there now but I still need to take the CV back off to replace the rubber manifold to CV adapter with a real CV manifold. I was planning on buying the proper jets and do it all at once. 185 and 45 are specified in my book. Would the 2003 road king headers and Kerker slip ons do anything to change that? Sorry for the lack of knowledge.

 

Go 48 idle and 190 main with a shim under the needle.

 

Jackpot, thanks. Running much better now.
